Key Features of Closed Loop Pressurized Solar Water Heater

• This series is used where the water quality is having more impurities - like places where there is hard water.
• These systems provide mains pressure pre - heating via highly effective Copper Coil heat exchanger located within the tank.
• The way in which the mains pressure solar collector heats water is the same as the non pressure solar reflector.
• Uses a 45-60 Copper Coil heat exchanger inside the tank which provides more than 1.2 m2 of each transfer area.
• When the cold water flows through the coil it absorbs heat from the hot water inside the solar collector tank.
• The solar collector tank is therefore a thermal store.
• The heated water is then collected in a separate tank which is circulated again to complete the cycle.
• The main advantage of this system is that the mains water is not introduced in to the tank so corrosion and scale build up is almost totally eliminated.
• The tanks are designed for low and medium pressure applications using gravity feed tank or pressure reduction valve.
